Remote host said: 550 5.7.1 message content rejected

Question

A sender from France is trying to send an email to us. Unfortunately his email is being rejected with the message below. I suspect there are some weird characters in the mail content but how can I allow the content to be accepted in our mail server. Thanks

Hi. This is the qmail-send program at somedomain.fr.

I'm afraid I wasn't able to deliver your message to the following addresses.

This is a permanent error; I've given up. Sorry it didn't work out.

Solution

Here is a relevant log entry:

Sep 16 11:18:49 mail postfix/cleanup[18651]: 150225EA1F3: reject: header To: <[email protected]>,??<[email protected]>,??"Lemestre cmm" <[email protected]>,??<[email protected]>,??<[email protected]>,??<[email protected] from mailhost.vvf-vcs.fr[217.109.xx.xx]; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<mailhost.frenchhost.fr>: 5.7.1 message content rejected

As you can see, it refers to the email To: header, and there are invalid characters in that header.

Your sender should check his mail program and ensure that it is constructing email headers properly.

What kind of MTA are you using? Does the message contain some attachments?

qmail, message rejected by qmail-scanner

@ALex_hha It is postfix. I've included the tag in the question.

[ALex_hha]

Where is mail log from your postfix?

[holasz]

I think I forgot to thank you. It indeed was the senders client. All sorted.
